What is the cost of shipping the engine and returning my core?

What do I do to return my core?

Once you have installed your new engine and have packaged up the core in the provided pallet making sure to fill out the warranty registration and core tag, contact our office at 901-553-9847 and we take care of the rest.

What do core deductions mean and what would cause a deduction to be made?

Core deductions are made when the returned core is not able to be remanufactured to DDTN Performance or requires more than the regular processes involved to repair. We stress that this is not a for profit charge and is to ensure every one of our customers receives the same quality of engine as the next.

NO CORE CHARGE WILL BE BILLED AT THE TIME OF PURCHASE, BUT BY BUYING YOU AGREE TO HAVE THE ENGINE CORE READY FOR PICKUP AND RETURN TO US WITHIN 30 DAYS OF RECEIVING THE ENGINE. FAILURE TO DO SO WILL VOID YOUR WARRANTY (UNTIL CORE CHARGE IS PAID IN FULL) THE CORE CHARGE IS 2500.00. IF YOU HAVE NO CORE OR THE CORE IS NO GOOD (CORE MUST HAVE NO VISIBLE CRACKS OR HOLES AND ROTATE 360 DEGREES) THEN THE ENGINE WILL BE SHIPPED IN SHRINK WRAP ON A NON RETURNABLE WOODEN & THE APPROPRIATE CORE CHARGE DUE.

ANY CORE ENGINES NOT RETURNED WITHIN THE SPECIFIED TIME WILL BE SUBJECT TO A RESTOCKING FEE OF 40%.

WE WILL NEED THE YEAR, MAKE, MODEL, AND VIN NUMBER TO MAKE SURE YOU ARE BUYING THE CORRECT ENGINE BEFORE WE SHIP.

How do I activate my warranty?

Supplied with every engine is a complete copy of our warranty with an attached warranty registration form as the back page. Once filled out it can be emailed to office@diesel.911.com.You should also retain a copy for your records as it may be required to assist with a warranty concern.

 

Do I need to buy new injectors?

Injectors are not a serviceable item and should be removed for testing or replaced every (90,000 mi). We like to remind our customers that an injector failure, especially from worn out or contaminated fuel system causing an engine failure is not covered under warranty.

Do I need a new oil cooler?

DDT Performance requires the replacement of the oil cooler otherwise the warranty will be void.

What do I do in case of a warranty concern?

  • Write down as much information as possible such as unusual noises, leaks, any lights in gauge cluster and what happened leading up to the incident.
  • During regular business hours contact DDT Performance at 901-553-9847 and we will promptly assist with the concern. After regular business hours you will need to have your vehicle taken to your nearest DDT Performance authorized repair centre or shop of your preference if none are available.
  • If ever unsure as to the severity of a problem it’s best to have your vehicle towed to avoid additional damages.
  • Once at a repair facility you will need to contact DDT Performance requesting a Warranty Approval Form. The shop will then need to perform the diagnostics necessary as to the failure and complete the form. The form then needs to be emailed to office@diesel911.com. Forms will be completed and returned within 1-2 business day stating what parts and labour will be covered.
